It’s wonderful what you can learn from tutorials & informative videos online. It’s so convenient to be able to watch a video on just about any topic that you desire to learn and come away with much valuable information in order to make sound informative decisions. I was glad to find a solid alternative to the conventional air conditioner options after seeing a series of videos on heating & air conditioner units. My older home doesn’t have a central air system nor HVAC ducts. So I searched the web looking for cost effective & energy efficient plans to cool our home without buying a less effective window air conditioner unit. I found a qualified heating & air supplier online. They flaunted the benefits of purchasing a small duct high velocity air conditioning especially for homes that don’t have a HVAC duct system installed. The small duct – high velocity air conditioner is close to the traditional air conditioning system that can be found in newer homes. It has the outside condenser equipment and the indoor coil unit. How it differs is by the way it distributes air throughout our home. Because of a lot of older homes weren’t designed for forced air heating, the small duct high – velocity air conditioning system is installed with the distribution system and the blower coil in the attic. This system also has a small insulated bendy tubing that is a mere 2 inches wide. A qualified Heating & A/C repair serviceman can install these between the walls, ceilings & floors without tearing them down. However after I finished seeing the video, I hit the stop button and instantly called our local heating & air conditioner provider.
